 * I installed 2.0.2 a couple of days after installing 2.0.1, according to the directions.
 * Now when I write any post and publish, I get the following error (but the post
   is actually published despite the error):
 * Warning: weblog_ping(): Unable to access /home/me/domains/mouseprint.org/public_html/
   wp-includes/class-IXR.php in /home/me/domains/mouseprint.org/public_html/wp-includes/
   functions.php on line 851
 * Warning: weblog_ping(/home/me/domains/mouseprint.org/public_html/wp-includes/
   class-IXR.php): failed to open stream: No such file or directory in /home/me/
   domains/mouseprint.org/public_html/wp-includes/functions.php on line 851

   851
 * Fatal error: Cannot instantiate non-existent class: ixr_client in /home/me/domains/
   mouseprint.org/public_html/wp-includes/functions.php on line 854
 * ============
 * Any ideas what to do to get rid of this?
 * Thanks,
 * Edgar

 * Was it all good after the upgrade and it has just happened?
    Or is this the first
   post since the upgrade?
 * Could be a plugin?
    Could be an incorrectly uploaded file?

 * Podz…
 * First post made after upgrading had this problem, and I haven’t installed any
   plugins.
 * I even re-uploaded functions.php in case something was wrong with the original…
   and that didn’t help.

 * I installed WordPress 2.0.2 yesterday and I get those exact error messages as
   well. But i’m not even upgrading. It’s a fresh install. Let’s compare notes dworsky.
 * this is what I get:

 * Reupload it one more time, but make sure you’re in ASCII mode, not binary?

 * for me THIS problem is solved, the “class-IXR.php” was “class-ixr.php” on my 
   server – it was case sensitive…
 * now i see, that sg is broken with the extended live archive. im using K2, maybe
   there is sg conflict between them
